Hi All,
As some of you noticed - there's no upgrade method for 12c to 19c mentioned in official guide. Any idea why is that?
I remembered for 11g to 12c, we can use DBUA (upgrade assistance method)
For Oracle 19c - there's only 'migration' option available
a) Do we need to uninstall Oracle 12c first then only install 19c - since the instance/sid will be clashed ?
b) Does the 'migration' actually indicate we're migrating to separate physical server for Oracle?
Thanks
